It's an absolute nightmare, OP you definitely are NOT BU! Yes, I am shouting!!
My OH has been a fan of a big London club all his life, and when we were childfree, although I found the constraints a bit irksome (dictated when we got married, when we could go on holiday etc) I was often off doing my own thing, so it was bearable.
However, after we had kids it causes the most arguments in this house. We moved an hour outside London, and every match takes up a whole Saturday or Sunday in travel and all the pre/post match crap. Even worse if it's a weekday match, as I often work in the evenings (instrument teacher) and am left to try and wrangle 3 small children to bed or get them to be quiet whilst I teach.
The worst thing about the fucking premier league BY FAR is the fact that they change the games all the time without any notice. So OH puts all the games into our shared calendar at the beginning of the season, but then there are huge numbers of caveats (if we win x then y game will be moved from Tuesday to Wednesday), but they also just move them according to TV schedules. So some arse in programming will suddenly decide to schedule a game and it moves from 3pm on a Saturday to 5.30pm on a Sunday or 8pm on a Tuesday. Often with little notice.
I can't plan, he will buy tickets for the kids the obligatory 2 months ahead of the match for a weekend game, only to find it's now a weeknight and they can't possibly use the tickets.
IT DOES MY HEAD IN. I HATE PREMIER LEAGUE FOOTBALL.
My advice to anyone contemplating marrying a serious football fan is - DON'T - unless you are a similar fan or you are not planning to have kids, or indeed any kind of a life that might involve holidays or planning of any kind during the football season.
I really really wish one of my 3 had arrived on a football match day, so I could have seen where his loyalties lie. He was relieved never to have been tested.
ETA He is a lovely man and excellent father in all other ways, and I hadn't realised (although he had tried to tell me) how all encompassing football is to him. This is our main bone of contention, and if he'd started as a season ticket holder when I was pregnant with my first I would have been livid
